72 hours
B
Correct answer
Explanation
The Earth completes one full rotation on its axis in approximately 24 hours, which defines our day.
A
Correct answer
Explanation
The Earth is an oblate spheroid, meaning it bulges at the equator and is flattened at the poles due to its rotation. It is not a perfect sphere.
